OPERATION
Risk of bodily injury or property damage.
•
This equipment should be installed and serviced by technically qualified personnel who are familiar
with the correct selection and use of appropriate tools, equipment, and procedures.
Hand/Auto Mode
When powered up, the drive reads the signal on Control Board J10 (Hand/Auto). If a Hand/Auto switch is not
used, the absence of a connection here appears as an open switch, and puts the drive in Auto mode. When a
Hand/Auto switch is used, an open switch puts the drive in Auto mode. In Auto mode, the drive controls the
pump to maintain a constant pressure.
If a Hand/Auto switch is connected to Control Board J10 (Hand/Auto), closing the switch puts the drive in
Hand mode. Hand mode runs the pump at a constant speed (default is 60 Hz, shown in the display). Hand
mode allows the drive to be run at full speed without a pressure transducer for longer periods of time as in
the case of new well development or system start up. Moving the switch back to Auto mode resumes the
automatic pressure tracking and control by the VFD.
System Status
When the drive is controlling the motor and pump, the display is illuminated
and the following information is shown:
1.
Whether the system is in HAND or AUTO mode.
2. Whether the motor is running (RUN) or stopped (STOP).
3. When using a pressure transducer, the system displays the current sys-
tem pressure in PSI.
When using a standard pressure sensor, the system displays the current motor speed (in Hz).
When running in HAND mode, the system displays the keypad frequency setpoint.
4. When using a pressure transducer in AUTO mode, the motor speed is displayed at the lower left of the
screen. In HAND mode, current system pressure is displayed.
When using a standard pressure sensor, this field is not displayed.
5. The lower right of the screen displays output current in Amps.
6. The Bluetooth icon indicates that the VFD is connected to a mobile device running the FE Connect -
SubDrive Connect Plus mobile app. A thermometer icon displayed at the left side of the screen indi-
cates the drive is in Over Temperature Foldback.
Fault Detected
If a fault condition occurs, the drive displays the Fault Code and Fault Description.
Several faults reset automatically, displaying a countdown timer until the reset occurs.
Pressing the DOWN button while the countdown timer is active resets the fault immedi-
ately. For faults that require a manual reset, turn off power to the drive (power cycle) and
restart after five minutes.
